Ammonia is commonly used as a preservative for natural rubber, but its high volatility and strong irritation to the human respiratory tract pose significant health risks. In this study, we utilized the layered two-dimensional nanomaterial Ti 3 C 2 T x (MXene) as an antimicrobial agent and synthesized MXene-SiO 2 nanocomposites by intercalating KH550-modified silica nanoparticles into MXene. This nanocomposite was then incorporated into a MXene-SiO 2 /low-ammonia preservation system. The results demonstrated that this novel system effectively preserved concentrated natural latex over a four-month period. Throughout this time, the volatile fatty acid (VFA) values remained below 0.1, the pH was stable at approximately 10, the mechanical stability time (MST) exceeded 700 s, and viscosity remained around 300 mPa·s—meeting the requirements for subsequent processing. The introduction of the MXene-SiO 2 nanocomposite into the preservation system had no adverse effects on the structure or performance of the dry film. The system exhibited excellent film-forming properties and promoted the formation of a cross-linked network in the vulcanized film. As a result, the tensile strength of the vulcanized film reached 22.87 MPa, a 64% increase compared to pure natural latex vulcanized film. this study provides an effective and environmentally friendly approach for preserving natural latex while simultaneously enhancing the mechanical properties of its vulcanized film.

Conductive hydrogel has garnered significant fascination for its potential as wearable sensor. However, designing a wearable sensor with excellent electrical conductivity, self-healing capability, mechanical strength and recyclability is still difficult to accomplish. Herein, a multifunctional composite hydrogel was fabricated via a one-pot method with cellulose microcrystals (CMCs) and MXene. The introduction of CMCs to the hydrogel composite provided mechanical strength and assisted in homogeneous distribution of MXene resulting the high electrical conductivity. The subsequently prepared conductive composite hydrogel exhibited improved tensile strength (87.4 kPa) and elongation at break (424 %) with optimum composition, outstanding electrical conductivity (1.11 S/cm) and quick electrical self-healing efficiency without external stimuli. The temperature responsiveness of the conductive composite hydrogel was mainly accredited for reducing interfacial thermal resistance ensuing of continuous heat conduction pathways. It also demonstrated the notable fire resistance offering quick fire-warning signals within ∼1 sec. The developed conductive composite hydrogel could monitor subtle human movements efficiently as well as possessed the ability to track human body temperature, indicating effective means of electronic skin (E-skin) for smartphone interfacing. This work introduces a feasible approach in designing an electrically conductive, biodegradable wearable composite hydrogel with potential applications as versatile motion, temperature and fire sensor.

Flexible dielectrics with exceptional dielectric properties are highly desirable for various electronic applications. In this study, we successfully fabricated CaCu 3 Ti 4 O 12 (CCTO)/Ti 3 C 2 T x MXene/millable polyurethane (MPU) ternary composite films via a combination of mixing and hot compression techniques. The incorporation of 2D Ti 3 C 2 T x MXene nanosheets at a mass fraction of 4 % significantly enhanced the dielectric properties of the composite films. Specifically, the dielectric constant at 100 Hz increased to 41.1, representing a 14.48 % improvement over the initial CCTO/MPU composite. Meanwhile, the dielectric loss remained low at 0.050, with only a marginal increase of 2.04 %. Additionally, the breakdown strength of the composite films was notably boosted to 19.15 kV/mm, demonstrating a 15.3 % enhancement. These findings highlight the substantial improvement in the dielectric performance of the CCTO/Ti 3 C 2 T x /MPU ternary composite films, showcasing their potential for high-performance electronic applications.

An appropriate electron transport layer (ETL) or cathode buffer layer (CBL) is critical for high-performance perovskite solar cells (PVSCs). In this work, tetrabutylammonium hydroxide (TBAOH)-functionalized Ti3C2Tx MXene (TBAOH-Ti3C2Tx) is developed to improve the photovoltaic performance of PVSCs. TBAOH-Ti3C2Tx is synthesized by HF etching and then TBAOH intercalation, and TBAOH can effectively attach to the Ti3C2Tx surface during the intercalation process. In hole transport material (HTM)-free carbon-based PVSCs with the structure of ITO/ETL/MAPbI3/carbon, the SnO2 doped by TBAOH-Ti3C2Tx (SnO2:TBAOH-Ti3C2Tx) as ETL shows decreased WF and increased conductivity and improves the growth of the perovskite film with a larger grain and significantly reduced defects, which synergistically facilitate charge transport and extraction and reduce charge recombination. The HTM-free carbon-based PVSC with SnO2:TBAOH-Ti3C2Tx ETL exhibits a significantly higher PCE of 14.93% with enhanced device stability compared to the control device with pristine SnO2 ETL (11.95%) and also outperforms most of the HTM-free carbon-based PVSCs with MAPbI3 perovskite reported so far. In traditional inverted PVSCs with the structure of ITO/PTAA/MAPbI3/PCBM/CBL/Ag, the TBAOH-Ti3C2Tx is utilized as a CBL to significantly enhance device performance with a high PCE of 21.16%, which is obviously superior than that (16.26%) of the control device without CBL. The impressive results indicate that tetrabutylammonium hydroxide-functionalized Ti3C2Tx MXene possesses great application potential in different functional layers for high-performance PVSCs.

Developing an advanced transparent conductive electrode (TCE) as a substitute for the fragile and high-cost indium tin oxide (ITO) is the top priority in the coming smart electronics era. Although two-dimensional transition metal carbides and nitrides (MXenes) have revealed great potential in the competition, the figure of merits (FoMe, defined as the ratio of direct current conductivity to optical conductivity) of reported MXenes TCEs are far below the minimum industrial requirement. Herein, we report on the breaking of FoMe limitation by a hybrid nanoimprint-blading technique to construct embedded MXene grids, where the fine slot channels are filled with MXene flakes and the space beyond is left empty, allowing more visible light to pass through, thus substantially improving the transmittance. Such a strategy decouples the correlation between transmittance and sheet resistance and achieves their individual regulation. As a result, we obtain an ultrahigh FoMe (∼84) surpassing most of other nonmetal TCEs and even being competitive to ITO. We demonstrate the application of MXene grid TCE in the electrochromic device, showing satisfactory switching time and excellent stability (>38,000 cycles). This work opens vast opportunities for MXenes to construct advanced flexible electronics for industrial applications.

A novel Cu/Ti 3 C 2 T X laminated composite foil was prepared using a combination of electroplating and electrophoretic deposition. The results indicate that the average thermal expansion coefficient of the Cu/ Ti 3 C 2 T X composite foil decreased by 11.26% compared to that of pure copper. Due to the high electron mobility of Ti 3 C 2 T X and the favorable Cu/ Ti 3 C 2 T X interface, the electrical conductivity of the Cu/ Ti 3 C 2 T X composite foil exceeded that of pure copper by 8.7%, reaching 6.2147 × 10 7 S·m −1 , and its thermal conductivity increased from 381.5 W/m·K to 423.5 W/m·K. The study revealed that a thinner, looser Ti 3 C 2 T X layer with fewer layers is more favorable for copper penetration and filling, enabling a continuous network-like structure and resulting in significantly improved thermal and electrical properties of the composite copper foil. These findings position the Cu/Ti 3 C 2 T X foil as a promising candidate for electronic encapsulation and super-conductivity. Graphical Abstract

Flexible strain sensors that combine high sensitivity and wide range are important for developing wearable electronics. In this paper, AgNWs/MXene/SEBS flexible strain sensor with high sensitivity and wide strain range was prepared using a thermoplastic elastomer (styrene-ethylene-butene-styrene) SEBS as the polymer matrix and AgNWs and MXene as the composite conductive fillers. The sensitivity of the AgNWs/MXene/SEBS sensor is significantly higher than that of the AgNWs/SEBS and MXene/SEBS sensors based on a single conductive filler. At 100% strain, the AgNWs/MXene/SEBS sensor has a sensitivity of 176.25. The sensor detects small strains of 0.5-5% as well as large strains of 5–50% with high linearity. The sensors remained stable after 200 cycles. The AgNWs/MXene/SEBS tensile sensors were subjected to array testing and finger bending recognition, and the sensors have promising applications in human motion monitoring. Graphical Abstract

Two-dimensional MXene materials have gained attention in optics due to their excellent conductivity and light absorption, showing great potential in applications such as photodetectors, photothermal therapy, and laser protection. However, the application of MXene in enhancing plasmonic biosensing on metasurfaces has remained largely unexplored. The MXene functional metasurface plasmonic sensor (MetaSPR), integrated with the advanced microfluidic technology (3MSPR device), enables real-time monitoring of antibodies in three critical fields: precision diagnostics, drug development, and expression process monitoring. The MXene-MetaSPR, retaining the layered structure and high conductivity of MXene, exhibits enhanced sensitivity through its synergistic interaction with the electromagnetic fields within nanoarrays. The sensitivity of label-free IgG detection is increased by more than 250-fold, with a detection limit of 2.56 ng/mL. Experimental results demonstrate that this system is capable of detecting high-affinity (pM) binding between therapeutic antibodies and their targets. Additionally, it enables continuous monitoring during the nanobody expression process in engineered bacteria, with a single antibody concentration analysis completed within a time scale of minutes. The 3MSPR device rapidly and efficiently captures the initial phase of kinetic curves, facilitating precise affinity analysis and optimization of expression efficiency.

Gold nanorods (AuNRs)-doped phase change materials (PCMs) hold great promise for alleviating the instability and imbalance of solar energy due to their exceptional energy storage density and adaptability. However, their poor full-spectrum light absorption and inferior stability lead to insufficient photothermal conversion efficiency. Herein, we devise functional PCMs with synergistic reinforcement of light absorption and photothermal conversion through the in-situ growth of AuNRs on the MXene surface. The results indicate that the bimodal resonance effect of AuNRs and broad-spectrum absorption of MXene synergistically endow a 29.7 % increase in light absorption efficiencies over the pristine composites, which is superior to the sum of the two individually doped phase change composites (PCCs). Similarly, the photothermal storage and conversion efficiencies of the AuNRs/MXene-doped PCC are significantly enhanced by 36.6 % and 78.4 %, respectively. Furthermore, the fluorescence analysis reveals a prolonged fluorescence lifetime of 1.91 ns and a low quantum yield of 0.27 %, demonstrating efficient separation and migration of light-induced carriers and thermal dissipation via non-radiative relaxation, which is because the AuNRs and MXene synergistically enhance the localized surface plasmon resonance effect and the spectral absorption bands. This work offers fresh perspectives on the development of advanced photothermal PCMs for efficient solar thermal applications.

Carbon nanofibers can be widely used in the field of electromagnetic wave absorption due to corrosion resistance, low density and good chemical stability. Here, we report a strategy to achieve strong microwave absorption capability by adjusting the crystallinity of carbon nanofibers containing Al 2 O 3 and TiO 2 . TiO 2 with Ti 3 C 2 T x MXene as a precursor decreases the crystallization temperature of Al 2 O 3 from 1400 °C to 800 °C in the carbon nanofibers. The diameter distribution of carbon nanofibers is uniform, though the surface of carbon nanofibers is getting rough with Ti 3 C 2 T x content increasing. The minimum reflection loss of carbon nanofibers is -55.78 dB at a thickness of 4.32 mm; the effective absorption bandwidth reaches 5.41 GHz (12.59-18 GHz) at a thickness of 1.67 mm, almost covering the Ku band. The excellent microwave absorption performance can be attributed to the synergistic effect of the non-crystalline carbon matrix and crystalline Al 2 O 3 /TiO 2 , in which the former improves impedance matching with free space, while the latter enhances the attenuation capability to the electromagnetic wave.

High-performance flexible humidity sensors are critical enabling components for next-generation wearable systems and electronic skin (e-skin), although achieving concomitant ultrathin geometries, mechanical flexibility, and ultrahigh sensitivity remains challenging. This study presents a significant advancement through the development of a capacitive flexible humidity sensor based on engineered Ti 3 C 2 T x (MXene)/graphene oxide (GO) heterostructures. The synergistic interactions between the polar surface terminations of MXene (rich in –OH and –F groups) and the facilitated water transport properties of GO are exploited to yield a humidity-sensing layer exhibiting a significantly enhanced dielectric response to moisture. The optimized MXene/GO device achieves a striking ultrahigh sensitivity ( S = 1.24 × 10 6 % ΔC/C₀), representing a 228-fold improvement over its pristine MXene counterpart, across a wide operational range of 11 % to 97 % relative humidity (RH). The sensor further exhibits rapid dynamic responses (adsorption/desorption times of 17 s / 7 s, respectively) and maintains excellent linearity (R 2 = 0.99). This work highlights the efficacy of MXene/GO heterostructures for developing ultra-sensitive flexible humidity sensors, paving the way for innovative applications in non-contact interfaces, skin hydration diagnostics, and physiological monitoring.

Current flexible piezoresistive sensors face the common problem that there is always a mutual limitation between high sensitivity and a wide measuring range, causing the current highly sensitive sensors to concentrate only on a narrow range. In this work, inspired by biological architecture, we design a needle-shaped column array decompression structure, combined with chitosan-modified polyurethane foam-coated MXene nanosheets as the sensor active layer. By leveraging the decompression of the needle column structure and the high elasticity properties of the porous structure, the piezoresistive sensor demonstrates a broad testing range of 550 kPa and a maximum sensitivity of 428.94 kPa–1 in the measurable range, which are 10 and 2 times higher than those of existing studies. Combined with medical devices, the designed devices can meet the testing requirements of different scenarios to accurately capture all kinds of training and human movement behavior recognition in the rehabilitation medical process. We provide a strategy in which introducing a voltage divider structure in the active layer enables flexible piezoresistive sensors to combine high sensitivity with a several-fold increase in range.
